 Between gdb HEAD 2004-06-03 17:47:54 UTC and gdb HEAD 2004-06-06
 19:02:08 UTC, a new regression happened in manythreads.exp:
 
   (gdb) info threads

   A problem internal to GDB has been detected,
   further debugging may prove unreliable.

 That makes four "GDB internal error" and "timeout" results with this script:
 
   gdb.threads/manythreads.exp: stop threads 1 (GDB internal error)
   gdb.threads/manythreads.exp: stop threads 2 (GDB internal error)
   gdb.threads/manythreads.exp: stop threads 2 (timeout)
   gdb.threads/manythreads.exp: GDB exits after stopping multithreaded program (GDB internal error)
 
 I am testing on native i686-pc-linux-gnu, red hat 8.0 glibc 2.2.93-5-rh.
 
 These are regression bugs in gdb.  When I run manythreads.exp with
 gdb 6.1 or gdb gdb_6_1-branch, all tests PASS.
